摘　　要：在室内培养箱条件下,研究了不同成熟度花生种子萌动期低温对花生出苗及幼苗生长发育的影响。结果表明:不同成熟度的种子受萌动期间低温的影响不同。种子成熟度好,活力强,抗低温能力强,出苗率高,幼苗根系发达、生长迅速整齐,单株叶面积大,有利于形成壮苗;叶片NR活性强,叶绿素含量高,有利于干物质积累。种子成熟度差,萌动期遭遇低温受影响较大,不利于壮苗,势必影响中后期植株的生长发育,降低产量。Effects of low temperature at germination stage on seedlings of peanuts with different maturation degree were studied. The findings indicated that the peanuts with good maturity had high activity, strong tolerance to low temperature, high germination rate, strong seedling roots, rapid and uniform growth, big leaf area, high activity of NR, increasing content of chl and high dry matter.
